Edge wear on duals?

[Wyley87]

What would cause my rear duals to wear on the outside edge? They've had the recommended 65psi in them since new and had regular rotations. Truck is right at max GVRW OF 13,600LBS. I had the truck weighed and the front and rear axle are maxed out. But I'd think with the recommended psi it would be ok.

If both outside edges on each tire, they are underinflated.
Do you have any pictures?

Not at the moment. I'd go out and take some but I'm stuck watching small children at the moment. Wife had to much fun last night lol. I'll try to get some later today.

Try running at the max psi the tire has listed, not the truck.

That would make the rating of the tires higher than the rating of the axle though right?

Not a problem as long as the load on the axle is not exceeded

True.

Just use the Max psi for duals though. Do you do a lot of maneuvering in tight spaces? That might cause it too...
